Pssssst . . . leftists sanctioned the burning of parts of Dem Party controlled cities -- along with looting, and all sorts of violence -- because of race. From 2008 through 2016 ANYTIME anyone criticized Barack Obama for ANYTHING leftists SHRIEKED . . . "Racist!" and "Racism!"
It's sort of like how the Left accuse the Right of violence when it is very nearly only ever the Left that resorts to violence.
